BINDING- MECHANISM.

To'all whom it may concern:

Be it known that I, BERT R. BENJAMIN, a citizen of the United States, residing at Oak Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Binding Mechanisms,.

tighter bundles to be bound for a given pres- I sure of the trip, reduce the friction in drivlng'home-the blnder mechanlsm, minim1ze the ad ustment necessary for wear, and provide a stronger construction which avoids wrong adjustment in the field.

These and other objects of my invention are attained by an improved construction wherein a stop is pivoted on the frame and connected to a bodily movable trip shaft in such a manner that upon bodily movement of the latter, the stop is oscillated about its pivot out of engaging position with the dog and held out of that positionby cooperating means until the dog has completed its second revolution, whereupon the stop is again returned to dog engaging position.

In the accompanying drawings I have, for purposes of illustration, shown oneembodiment which my invention may assume in practice.

In these drawings: Figure 1 is afront view of a binding mechanism equipped with my improvement, showing the parts in dogengaging and releasing position. Fig. 2 is a view similar to Fig. 1 showing the parts in the position occupied by them during the discharge of a bundle. Fig. 3 is a detail plan view of the trip stop. Fig. 4: is an end view of the trip. stop mechanism.

As in the usual construction, a binder frame or head 1 is disposed over the deck 2 of the binder. Upon the head is carried the usual binder mechanism including the needle 3 and discharge arms 4:, the needle being connecte to the usual needle shaft {3 and Specification of Letters Patent.

application filed January 31, 1916. Serial No. 75,402.

- through a link and crank connection 6 with a carnwheel 7 which is mounted on a rotating shaft 8 carrying the discharge arms 4. Cooperating with a cam 9 carried by the wheel 7 is a cam engaging member or roller l0'connected through a member 11 with a link 12, which is in turn connected to a crank 13 on the compressor trip shaft 14 carrying thecompresso'r trip 15. As in the construction described in my previous Patent, No. 994,711, this shaft 1 1 is bodily movable relative to the binder head '1' when the trip is actuated and means are connected thereto engageable with the rotating dog 16 of a binder clutch 17 which connects the binding and discharging mechanism to the power shaft 18.

In my improved construction a trip stop 19 is pivoted at 20 upon an extension 21 on the binderhead 1. This trip stop is provided with a grainwa rdly extending portion 22 engageable in extreme upper position with a lug 23 on the head 1, and this portion 22 is provided with a -laterally extending end 2 1 thereon engageable with the dog 16 of the binder clutch 17. As shown, this stop member 19 is also provided with a slotted portion 25 to enable it to move relative to the usual transverse pipe 26 and is provided at its stubbleward end with an upwardly extending portion 27 which is'pivotally connected by a sleeve connection 28 with the shaft 1 1 at a point adj a cent and within the crank, 13. The stop 19 is ,also provided with spaced arcuate lugs 29 and 30 disposed above its pivot and engageable with a cam'31 rotatable with the needle shaft 5. As shown, this stop 19 is also connected to the frame by means of a rod 32 pivoted at 33on the binder head at a point above the pivot 20, and extending through a laterally extending lug 3 1 on the stubbleward end of the member 19, a coiled spring 35 being disposed about the protruding end of the rod and held in position thereon by an adjustable nut connection'36 by which the tension of the spring may be adjusted.

In the operation of my improved mechanism, it will, of course, be understood that the parts will occupy the position shown in full lines in Fig. 1 prior to the actuation of the trip-15. When, however, the pressure 9f grain against th s tr p f rc the same backward, the end of the shaft 14 shown herein will be moved bodily toward the left from the position shown in full lines in that figure, to the position shown in dotted lines in that figure, the trip 15 likewise assuming the dotted line position. This movement, obviously, swings the stop19 about its pivot 20, causing the same to as sume the dotted line position shown in that usual and the crank connection 12 thereof will be lowered in such a manner as to lower the trip 15 to the position shown in Fig. wherein the grain bound by the needle may be discharged from the deck by the discharge arms 4 without conflict with the trip. During this movement it will be noted that the stop 19 is through its connections swung backward still farther about its pivot from the position shown in dotted lines in Fig. 1 to the position shown in full lines in Fig. 2, wherein it engages with the lug 23 on the binder head 1. Obviously, the stop member 19 will be held in that position by the action of the cam 31 on the lug 29 until after the clutch dog 16 has completed two revolutions, whereupon the cam wheel 7 will cause the connection 12 to again be raised to raise the trip 15, and since the needle has then returned to its normal position, shown in full lines in Fig. 1,'under the action of the spring 35, the same will remain in that position during the remainder of the third revolution of the clutch dog 16 and interrupt the movement of that dog when the latter has completed itsthirdrevolution, the parts then being in their normal position and ready to bind another bundle.

In the operation of my improved mechanism, it will be noted that the trip stop has relatively little movement and a very small amount of wear upon the same, practically all wear being taken on surfaces of a character well adapted to long service. It is further to be noted that the construction is exceedingly simple, involving a small number of parts which may be very readily manufactured and assembled and that the mechanismrequires little or no adjustment, the

parts is relatively small as compared with ordinary binder mechanisms. These and many other advantages of my improved construction will, however, be apparent to those skilled in the art.

lVhile I have in'this application specifically described one embodiment which my invention may assume in practice, it is, of course to be understood that this form of the same is used for purposes of illustration and that the invention is not limited thereto, but may be embodied in various other arrangements and construction of the parts.
